Hi Guy's Just thought I would show you my latest project, it is something that I tried a few years ago and have just revamped it because it worked so well back then.
I am currently using it to just do filler and finish coats but I have also laminated on it.
Yes they do come off the rotater flat surfaced and I have coated boards in both standard resin and epoxy and both are great.
My theory was to get an even coat of resin over the whole board at once, the curving shapes of the surfboard and the rotation allows centrifugal force to hold the resin in place.
I never liked the idea of resin falling off the boards as you filler coated the decks and filling the concaves as you coated the bottoms.
This way you get less waste and I mean you might get a tea spoon of resin that hits the floor and filler coating set fins is unreal, it leaves them coated perfectly even.
It saves time and there is also a complete bond instead of overlapping joins, the rails are smooth as silk and therefore sanding of the rails has less chance of bringing up weave.
How are you actually applying the resin to the board? By traditional methods? Is this just a way to allow the applied resin to cure evenly via centrifugal force?
Awsome device! Simple idea too.....(these tend to be the best).
However I dont think centrefugal forces come into it much. This force acts perpendicular to the rotation axis, if the device was rotating a lot faster, you'd see the resin is still dripping of the bottom of the board, thus making the device useless. I think gravity is the main force at work here. Gravity pulls on resin in one direction, however since the board is rotating, this direction is constantly changing....goes.....ahem..... full circle so to speak :)
I think what essentially happence is the resin slowly flows back and forth, and has no time to pool into drops and drip of the board.
What do you do in the nose-cone and tail area where the board is attached to the machine? Do you have to touch those up after the board is taken off the rotisserie?
…hey man, think I remember you years ago when we (members here) were discussing about shape designs and remember your profiler machine…then you quit a bit angry but I can t remember why
pretty interesting that at that low speed no problems occurs with the resin dripping, etc
It looks a whole lot like the rotisserie that I use to dry my flies on so the head cement dries evenly and doesnt sag.
I would love to see the resin applied. It would allow you to hotcoat both sides and spin it out to keep a uniform shell of resin on both sides of the board at one time.
Just seems like it would make for an extra step with the nose and tail attachments.
Hawaii and Israel are on the exact opposite of the globe.
this means that your up is my down and my down is your up...
and....
this means that if you hotcoat a borad's deck at your place , I can come with my Israeli-gravity-oriented resin and brush a hotcoat on the bottom of your board while you're doing the deck.
my resin will drain upwards while yours downwards .
For a start I am not trying to sell the system, I had an idea and I tried it.
For me it works better than the way I was doing it before and that's all that matters.
For those who would like to know how I am doing it:
I Lam like normal (on standard racks) but once it kicks I filler coat the tip of the tail and the tip of the nose(no major added process) when that goes off I put it on the spit.
I rotate it so the bottom of the board is facing up, filler coat as normal, then rotate and stop so the deck is facing up, do the same and then set it spinning.
The rotation is slow enough to give it another brush all over as it is spinning without resin falling of the board, this evens it out more and by the time it kicks it settles flat.
When it comes off the spit the rails are as you shaped them with an even thickness all over( no build ups or tape lines).
It is fantastic with epoxy because it speeds up the time frame of waitng for epoxy to cure enough to be flipped.
I also believe it is a better bond because the whole board is coated at once and you are not relying on a mechanical bond of overlapping top and bottom coats.
Yes it is simple and that is why I showed it to the crew here, its not expensive to make and they might want to try it.
I make boards for a living and have done for over thirty years, if it didnt work I definatley would'nt use, it let alone post it here.

(Hey Wildy thanks for the positive reply, I hope their treating you well at FW.)
I for one think that it is a pretty sweet system especially with the time savings to be had on epoxy. If you took my question as criticism, I apologize it wasnt intended as such.
Thanks for the explaination. Now I am off to strip the rotisserie off my grill.
Howzit Lee, Unfortunately I have moved from Kauai after 40 years and am now living in Arizona. Stopped building boards after getting cancer and it's possible the chems may have contributed to me getting it. After thousands of boards I miss building them sometimes, but then I think about my health. Like your idea though as funny as it is. Aloha,Kokua
